摘要

Background and Objectives: Malnutrition and energy metabolism disorders are characterized by a low respiratory quotient in patients with liver failure and often lead to poor prognosis. Therefore, early nutrition interventions are crucial for patients with liver failure to ameliorate abnormal metabolic status and malnutrition. This study explored the effect of an individualized nutrition intervention on the respiratory quotient of patients with liver failure. Methods and Study Design: An individualized 2-week nutrition intervention was conducted on patients with nutritional risk caused by liver failure according to patient resting energy expenditure. Patients were separated into two groups for further analysis according to whether their energy intake reached 1.2 times their resting energy expenditure. Results: Fifty-two patients with nutritional risk caused by liver failure were enrolled. Their average respiratory quotient was 0.79 (0.76-0.84) at the baseline. Patients with an energy intake of ≥1.2 times their resting energy expenditure had a higher respiratory quotient and lower scores on the model for end-stage liver disease and Child-Pugh test than those with an energy intake of ＜1.2 times their resting energy expenditure at weeks 1 and 2 after the intervention. Moreover, no significant differences were observed between the two groups at the baseline. Respiratory quotient was negatively correlated with the model for end-stage liver disease and Child-Pugh scores. Conclusions: Individualized nutrition interventions with an energy intake ≥1.2 times the patient's resting energy expenditure can effectively improve the respiratory quotient and reduce disease severity in patients with nutritional risk caused by liver failure.
